Abstract

In a radial piston machine which includes a driven rotatable rotor with radial pistons displaceable in radial recesses of the rotor by pressure medium and carrying rollers which cooperate with a cam track of the rigid cam plate, the length of the rollers can be increased due to the provision in the bores receiving the rollers respective opposing recesses in which portions of the roller are received.
